Lode Runner on the ZX81?

[dr beep]

Let me make first remark: controls will get multiple keyreading for i.e. up and right together.

It's really nice I think the speed is just right. The movement feels very smooth. I'm excited to see how this game works out!

Collecting gold : working
Display escape ladder : working
Uptheladder to next level : working

To do :
Digging
Repair of hole
Movement enemies
Score
Dead (also by suicide)
Better controls

Nico to do:
Display of same brick on fakebrick and test field in compressed data.
(If not too slow, better visible screen)

Extra's:
User defined keys
ZXPAND Joystick

NOT:
Leveleditor, due to compressed levels and the effect any change will have on the leveldata.

Digging now added.

Only repeater must be shut down.
Now too fast in digging holes.

After that ....
Timer for rebuilding holes

EDIT:

digging had few bugs, now repaired.
Next : rebuilding walls.

Score line now added.

Some errors in the levels found.
The levels are compressed, smaller than on the ZX Spectrum.
Some levels are unplayable due to found errors or very hard, so some adjustments are needed.

Now during printing of the level the coordinates of the enemies are stored for later movement.

Short in time, but today I altered the timing of rebuilding the digged holes. Now they react more like the original.

[dr beep]

Player gets killed when trapped inside rebuilding digged holes.
Enemy kill is found, but no movement yet so no dead either.

Is that screen correct? There is a "ladder" in the right picture (top right), while there is a "wall" on the left picture.

First of all, the level is compressed to fit a smaller screen.
Second. due to compression the gameplay is different (can't walk underneath)
Third. Yes, ladder is different.

The level needed adjustment so now it is as playable as on the ZX Spectrum.
Same to do for 2 other levels with errors
